I am trying to create an ios Wallet Event Ticket. I managed to give all the info I needed to create the pass.json and I have signed and zipped it. When I try to open this on a Mac, I am able to see the pass in the preview. When I email it and try to open it from an iPhone, the screen just goes to the main screen as if it crashed.
After lots of experimentation I found out that if I add at least one of t he images (icon) I am able to see it in preview and add it to the Wallet.
Since I do not care to add any image, this seems way too much just to make it work.
The question is, are images required in the pass? And if not, why does it not work without them. I repeat, it was displayed on Mac preview either with or without the image file.
